Variation of crystallite size of Al1-xInxN for different values of x and band gap

V. Naik; Ratna Naik; H. Somashekarappa; S. S. Mahesh; R. Somashekar

By using wide angle X-ray scattering (WAXS) technique, we have characterized the epitaxial Al1-xInxN films (thickness, 150 nm) with 0 <x < 1 grown by plasma source molecular beam epitaxy on sapphire (0001) at the low substrate temperature of 375°C, by computing the crystallite size in these samples. We observe that the crystallite size decreases with increase in the concentration of indium and that the band gap in these samples has a direct correlation with the crystallite size.
